Abstract
The invention discloses an anti-yellowing finishing method for a silk fabric. The anti-yellowing finishing method comprises the following steps: preparing an anti-yellowing finishing agent of the silk fabric; dipping the silk fabric in the anti-yellowing finishing agent, and performing twice dipping and twice rolling at normal temperature, wherein the take-up rate is 100%; and drying the silk fabric, taken out of the anti-yellowing finishing agent, at 40-60 DEG C for 10-20 minutes, and baking at 120-150 DEG C for 5-10 minute. The silk fabric subjected to finishing by the method has a good anti-yellowing effect, is soft in handfeel, and is endowed with certain washability.
Description
Technical field:
This invention relates to the technical field of silk fabric, relates to a kind of yellowing-proof finish method of silk fabric specifically.
Background technology:
Silk fabric is being processed, is being used and easily yellowing in storage process, and fiber embrittlement, powerful reduction, serviceability and presentation quality decline simultaneously, therefore, carry out yellowing-proof finish have great importance to silk fabric.
The yellowing of silk fabric is that fibroin interior molecules changes under the impact of the external environments such as Ultraviolet radiation, moisture, oxygen, makes silk fabric outward appearance present yellow.May cause in fibroin macromolecular chain yellowing mainly with the amino acid of aromatic side chains, as tryptophan, histidine, tyrosine, phenylalanine, proline etc.Structure, the chemical activity of phenylalanine and proline is lower, is difficult to change under Ultraviolet radiation, even and if change, generate the possibility of coloring matter less.Therefore, tryptophan and tyrosine are the primary amino acid causing real silk xanthochromia.
Yellowing-proof finish method conventional at present comprises: ultra-violet absorber arranges, antioxidant arranges and RESIN FINISH, first two method for sorting Be very effective, but general ultraviolet absorber and antioxidant are all very easily water-soluble, the washability of the silk fabric after arrangement is poor; Although RESIN FINISH makes silk fabric have certain anti-yellowing performance, irradiating its anti-yellowing effect in the sun for a long time can reduce.
Summary of the invention:
The object of this invention is to provide a kind of yellowing-proof finish method of silk fabric.The anti-yellowing of silk fabric after the method arranges is effective, soft, and has certain washability.The method is simple to operate, and cost is low, to environment and body harmless.
Object of the present invention is achieved through the following technical solutions:
(1) the yellowing-proof finish agent of silk fabric is prepared;
(2) be immersed in by silk fabric in above-mentioned anti-yellowing finishing agent, then normal temperature two soaks two bundles, and pick-up is 100%;
(3) take out silk fabric, 40-60 DEG C is dried 10-20min, and then 120-150 DEG C bakes 5-10min.
Preferably, yellowing-proof finish agent described in step 1 comprises 2-hydroxyl-4-methoxy benzophenone-5-sulfonic acid, thiourea resin and ammonium acetate.
Preferably, in yellowing-proof finish agent, the concentration of each material is 2-hydroxyl-4-methoxy benzophenone-5-sulfonic acid 0.5-2%, thiourea resin 5-10%.
Preferably, bath raio when silk fabric is immersed in yellowing-proof finish agent in step 2 is 1:20-1:30.
Beneficial effect of the present invention is: cause the topmost reason of silk fabric xanthochromia to be ultraviolet in daylight, and 2-hydroxyl-4-methoxy benzophenone-5-sulfonic acid adds in silk fabric, it is easier than silk fabric absorbs ultraviolet, silk fabric itself is not decomposed, and can also decompose with silk fabric the free group produced and react, make it lose activity.Thiourea resin and fiber generation crosslinked action or thiourea resin self polycondensation form three-dimensional space network structure, and it can fix 2-hydroxyl-4-methoxy benzophenone-5-sulfonic acid, makes the silk fabric after arrangement have certain washability.The method is simple to operate, and cost is low, to environment and body harmless.
